1912. Serial No. 724,680.

Be it known thatv we, GEonGE A. Doynn and STEPHEN A. DoBYNE, citizens of the and residingatSt. Louis, in the State of Missouri, have invented certain new and useful Improvements in Fastener of which the .following is a specification. l This invention relates to fastener inserting or nailing machines, and more particularly to machines of vthe classl known es string nailing machines. v

This application is a ontinuatlon of our application Serial No. 593357, filed Nov. 21,`

1910 as to subject matter Vwhich is common to the two applications;

Where a string nailing'machine .is to'bev used for forming a seam, for instance a seam for attaching a sole to a shoe, it is neces,- sary to provide lsuch a machine with an awl mechanism. It is y and lthe thro-at be moved alternately into the line of drive, in. order to properly position the awl-hole made in the work to receive the fastener'.A Itis important that the string of connected nails be properly fed into the throat and that the lowest nail be properly severed from the string 4so that the-headwill and clean. v

One of the objects of this invention there# fore is to construct the machine so that the string will be properly and accuratelyfed be cut ofl" square 5 linto thel movable throat, and so that the nail will be properly severed from the string so as to forma square cut head.

In a 'McKay shoe, a transverse ,section of which is shown in Fig. 22, the` fastening means passes through the outsole, upper?4 and insole7 and sometimes through va tofore the sole of a McKay shoe lwas-attached by a sewed seam. The McKay sewing machine used for performin this oper# ation is however, a very comp cated mait leaves the projecting chain on the'insole, and the shoe therefore requires a socksole to cover `up'this seam. Various methods have been proposed for securing 'the sole lof a tapsole 'vlocated between the upper and insole; Here-- McKay shoe by without success. should run close and therefore as the upper as possible, in order to make a, tight seam which will present a neat appearance. VVherea metalli-c fastener seamis used, it is desirable and necessary that the points of the fasteners The seam in a'McKay shoe to the conto-ur of the sole,

close to the inside face of clenched 'in the ina metallic fastener seam, but(4 sole extend along the seam. This requires, that the-clenching mea-ns be constructed so .i

Another object of this invention therefore I is to construct a machine which will form a seam producing a flexible sole, and to pro- Vide means" for absolutely predetermining the direction of the elench` of the fastener, so that the fasteners of the'seam may have .their points clenched inthe direction of the seam. y

Another object iste-provide means whereby the throat will be operated positively in both directions, and tov construct the guide `for the fastener stock so'as to insure apositive and accurate :feed of the fastener stock. Another object is toprovide al positive and direct driving means for the driver, the driver bar, :and the awl, and to provide means for the accurate :adjustment of said members.

Another object is to improve the machine upper and ruin .the-

f as tn certain detailsb of construction, and

yfurther objects will appear from' thedetail'- description taken in connection with the accompanying drawings in whlch:

Referring to the accompanying.drawings,- 20 designates the machinel head er frame., which is bolted upon a pedestal'r column as is usual in machines of this type, and 21A designates a horn of usual construction pro-f vided with the usual cupped-clenching anvil. A main drive shaft 22 is mounted in the head and has rigidly secured thereto a cam Wheel 23 and at its forward end a crank 24. The machine is provided with spaced bear ing lugs 25 and 26 positioned Arespectively above and below the drive shaft, and these lugs are bored to form bearings for a driver bar 27. A driver 28 is removably clamped in the driver bar by means of a set screw as shown in the drawings. The upper end of the driver bar is provided with a head 29 which has a rearward extension 30 forked to embrace a guide bar or post 31 on the lmachine head, one of the lugs 32 of the fork being adjustable as shown in Fig. 2 to take up wear. A pitman 33 connects the crank 24 with a bearing 34 on the head 29, the end 35 of the pitman beingsplit as shown at 36. An eccentric sleeve 37 provided with a lmurled head 38 is rotatively mountedin the end 35 and on the bearing 34, and is secured in position by means of a screw.

and Awasher 39. The split end of the connecting rod is arranged to be contracted to clamp the eccentric sleeve in adjusted position by means of a locking screw 40 having" a knurled head. By means of this con struction the driver may be adjusted vertically by first loosening the locking screw and then turning the eccentric sleeve,

the parts may then be locked in adjusted lposition by clamping the locking screw.

A presser-foot 41 slotted as shown in the ldrawings is provided with a shank '42 screwed to the head. A driver guide has a shank 43 secured to the head by means of a screw 44 and dowels as shown in Figs. 1, 4 and 7. The lower end of the shank' has formed thereon a driver guide 45 which is bored to receivel a sleeve 46 of novel'iconstruction and shown in detail in Fig. 9. The lower end of the driver. is of rectangular construction and hasits longest dimension transverse of the machine.l The sleeve 46 is bored at 47 to receive'the driver and is -provided at itslower end with a saw cut 48 to furnish an angular guiding portion for the angular part of the driver. This construction of th'esleeve reduces its cost of manufacture. The sleeve` is secured in 0- sition as shown in Fig. 8 .by means of) a at 511" The driver may be removed by` lloosening and raising the sleeve outI of its support, loosening the'l driver, and then turning and removing the driver through the slot 51. l

A- throat 52 is provided'l with a shaft 53 supported in spacedbearings 54 and 55 lon the machine head. An arm 56 is secured on this shaft and is engaged by a spring pressed plug 57 sliding in a bore 58 in the machine head, and this plug normally tends to rotate the shaft and throat to the right Figs. 1 and 4 into alinement with the driver and into engagement with a stop 59 on the machine head. A lever 60 is supported in vided at its lower end with an adjustable' set screw 62 engaging a laterally extending lug on'the arm'56, vand at its upper end with a cam roll 63 engaging the cam 64 on the cam wheel 23. The cam and lever operate to positively'return the throat into alinement with the driver and into engagement with the stop 59. l

A fastener stock guide 65 is provided with an ear 66 having a lu 67 thereon which has a bearin in a bore 1n the end of the shaft 53 so t at the throat and the guide will move about concentric axes. The guide is secured in position yby means of a screw 68 extending through the ear and lug and into the shaft 53. An arm or pin 69 is lformed on the guide 65 and this arm is held in engagement with a stop 70 on the machine frame Aby means of a. comparatively strong spring 71. Tho-guide Iis pro- '-vided with.a-groove 72 for receiving the string of" connected nails.V A resilient plate 73 yis pivoted at 74 on the guide, and is ro- -vided with edge portions 75 and 76 of di erent lengths adapted to engage the heads of lzo ledges or portions 75 and 7 6 over the groove 72. The screw 74 is drawn up tight soithat the plate will be held frictionally in either of its adjustedpositions. The plate forms a guard or detent adapted to prevent backward 'movement ofthe string and for conposition by. means of clamping screws 82.

The arm 80 lis pivoted at83 to one end of a lever 84, and a spring 85 is constructed to tend to move this arm in a counterclockwise direction (Fig. 1) on the lever. The lever 84 is pivoted at 86 upon the machine head, and is provided with a ,forked end 87 embracing an eccentric 88 onv the drive shaft. j

A tie holt 89 connects the ends of the fork. The throat is provided' with a` depending portion 90 working in the slot in the 'presser-4 foot and is cut away or channeled at one side. AA block or guide member 91 is pivoted in this cut away portion at'92, and this block is provided with a iin 93 which pro- A jects into the ldriver passage 94 and forms l. 107 in the cam wheel.

one wall of the driver passage. Theblock is held with its fin in the driver passage by a spring pressed plug 95 bearing against the block and mounted in a tubular bore of a part 96 secured to the throat.

able cutting die 97 which is bowed as shown in Fig. 12 and has its notched cutting edge slightly beveled or undercut as shown at 98 Fig. 4. The upper face of the throat andl die adjacent the driver passage is curvedA on the arc of a circle concentric withA the throat pivot, and due to the fact that the guide is' nailV shank. The die 97 is clamped on the throat by a screw 99, and the bowed construction of the die will cause the die to be firmly clamped on the throat at itscutting ed 0e..

iin awl carrier 100 is provided with an awl 101 and has a shank 102 supported -to rock and slide in a bearing 103 on the machine head. The `awl carrier is rocked from the cam wheel 23 by an arm 104 on the carrier connected through ablock 106 with the forked end -of a lever 105 pivoted on the machine head, the upper end of the lever having a cam roll engagingA a. cam groove The awl carrier is slid in its bearing by means of a lever 108 pivoted on the machine head and provided The upper. face of the throat is provided with a removat its upper end with a cam roll 109 'engagingl a face cam groove 110 in the cam wheel. Thelower end of the lever 108 engages the awl carrier throughA a screw 111 which is adjustably mounted in the endl of the awl carrier yas shown in Fig. 13 and is for this purpose` provided with a slotted head. A.

spring 112 is mounted in the bearing 103 and between the end of the bearing and the hollow shank 102,-an'd this spring tends to move the awl carrier to the right Figs. 1, 4 and 13. The awl carrier shank is threaded as shown at 113 to receive the threaded shank-l 114,

which extends through the end of thebearing .103, and is provided with a knurled head 115. The threaded shank 114 is arranged to be adjusted by means of the knurled head,

and this head is provided with notches 116A I arranged-to be engaged by a yielding latch 117 mountedn the 4bearing 103; A leather washer 118 is interposed between the knurled head and the end of the bearing 103. The awl carrier is operated from the cam wheel through itslevers, and it will be noted that these levers are operated positively' in both directions. 'l The carrier is slid in its bearing by means of the lever 108 andis returned by mea-ns of the spring 112. Its return movement is however'- limited by the engage ment of the knurled head with the end of the bearing, the washer 118 forming a cushion to take up the impact. The feed of the awl may therefore/be adjusted by adjusting the knurled head, and the latch is'long enough so that it will remain in engagement with the knurled head during its slid-in movement with the awl carrier.l The aw may be properly alined with the line of drivel by adjusting the screw 111..

The fastener stock, which is in string nail form, is supported from one or more reels mount-ed 'by means of a bracket 121 on the machinehead. In order to support the free ends -of the fastenerstocknot in use, the machine head has mounted thereon a plurality of clips 122. One of these clips is shown in detail in Fig. l0, and Acomprises a shank 123 and a pair of lugs 124 flaring out? wardly. The whole clip is preferably made" .ofsheet` metal and the lugs thereof are yielding and may be spread apart to receive swungto cause the awl to pierce the Work j -by means of the lever 105, and is slid to feed During the feedingA .the work by means of the lever 108, the awl A position shown in Fig. .4, the cam roll 63 belng at this time on the low part of the cam 64 to permit such movement. As the throat moves from the position shown in Fig. 1 to the position shown in Fig. 4, the feeding and cutting member 78 moves down and feeds the string of nails into thethroat, thereafter thefeeding and cutting member is moved to the right Figs. 1 and 4 to cut off the lowermost nail from the string, and thereafter the throat is moved to the right to the position l shown -in Fig. 1, when the driver descends to drive the nail positioned in the throat, the throat being returned to its position in the line of drive by means of the spring pressed plug 57 and the positively operated cam lever 60. It is thus insured that the throat will be returned into the line of drive before the driver descends so as to obviate breaking of the driver. During ,the operation of the machine the throat is moved into and out of alinement with the driver and with the string nail guide. The cutter also operates to move the stringpnail guide to place the groove therein in alinement with the throat, and in the actual operation both the thro-at and the nail guide move simultaneously toward and from each other. The cutter engages the top face of the thro-at and is then moved to the right Figs. 1 and 4 to cut the last nail from the string. In Fig. 4 the parts are shown in position just after the nail has'been severed. The cutter is now under tension and bears not only with considerable force against the string nail guide, but also upon the upper face ofthe throat. passagexis wider at the top than the head of the nail so as to permit the lowermost nail to start to feed into the throat as the throat and string nail move into cooperative position. If now the' throat is moved back to position while the cutter bears thereon the nail positioned in the throat is liable to become misplaced by thecutter, thus causing 4breakage of the driver.

In accordance with this invention the eccentric 88 and 'the' cam 110 are so constructed and so positioned relatively on the drive shaft and with respect to their fork and cam Aroll, that the-pressure of the cutter on the upper face of the throat will be relieved 'oefore the throat starts to swing back into alinement with the driver. This is shown in- Fig. 4. In this` figure the eccentric 88 is atl dead center with respect to its fork and is ready to start to move the lever 84 clockwise.

The cam A110 is however, at this time in full engagement with its cam roll 109 and will remain in engagement therewith while the drive 'shaft turns through a 'short arc.` The lever 84 will therefore .be swung on its pivot for a short distance in a clockwisev direction The driver The pressure of the cutter on the throat and on the head of the nail in the driver passage is thus relieved before this throat starts to move back into alinement with the driver. The parts are so arranged as toy raise and retract the cutter a short distance from the upper face of the throat before the throat starts to move back. As the pressure of the cutter is thus relieved, this cutter will not j bear upon the head of the n'ail inthe throat,

'so that this, nail is not displaced when the abutment for the head of the plug 95. The

guide member can bc readily removed by removing the screw 92 when the guide member can be pushed downwardly outof its channel. The shoulder 133limits vthe movement of the plu@ when the guide member is removed. The fin and the spring plug, the spring of which is comparatively strong, operate to retain the guide member in position in the throat even when the pivot pin or screw 92 is removed.l

'The guide member 91 is arranged to move towardand from the opposite throat wall at both ends, since the lower end is free and the upper end has a loose connection with its pivotI 92, and since the plug 95 bears against' this guide member at a point intermediate its pivotal connection and its free end. The construction of the fin is such4 that it will constantly and at all times bear against two separated points of the head side of the string nail during the entire passage of this nail through the driver passage, and this engagement is at the head and a point on the shank of the nail. The nail will thus be .held firmly with its fiat and straight side In Figs. 16 and 17 is illustrated the opera.-

tion of cutting a nail from the stringlvor fastener stock. As the lowermost nail 134 from the stringf135 is fed into the. throat, 13o

the angular displacement of the throat with respect to the string nail guide will cause a bend 136 in the string between the lowermost nail and the next one 137 above it and at a point just above the head of the lowermost. nail 134. The formation of this bend is iniportant as vvill hereinafter appear. The bend 136 formed as described above is however curved too much and on toolong an arc to be useful and must be partially straightened out; this is accomplished as hereinafter' described. As the cutter moves against thefI die 97, the lowermost nail is severed from the string andthe bend 136 will be partially straightened out by the pressure of the cutter Vbearing against the nail 137 `and against the guide 65, which guide is sustained by the spring 7l Whichis comparatively strong. While thenail 137 has its bent'portion partially straightened, the eXtreme end will remain slightly turnedas `shown in Figs. 17 and 24. This turn Will be even slightly more 4abnupt than the bend 136, due to the straighteningv action of the cutter and in part due to the action ofthe beveled and undercut cutting edge of the die on the string. The cutter 7 8-does not in this case perform the usual operation of a cut- `ter, but operates rather as a die. The actual cutting is performed by the undercut cut-l ting edge of the die`97. The point of the cutter does not dig into `the string, but rather operates to clamp thestring Vandyform an abutment shearing edgei'vvith respect l,to the edge of the die 97. The bevel face 138 ofthe cutter is ground oif to such' an angle that it is substantially parallel with the edge- 139 of the nail. The cutter does not there-l fore dig into the material, butvv the actual shearing is performed by the die 97 which cooperates with the cutter in inishingtheslightturn on the point of the nail.. The nail -as thus formed will have its point slightly but abruptlyturned as shown in Fig. 24. 'This is important in-'the utiliza-1 tion of-4 a machine for driving fasteners into leather, since it predetermines the direction of the clench of the nail, and Will cause the anvil to clench the point in a predetermined" direction'asjshown in Fig. 4. The anvil used withmlchines of ,this type is of the ordinary cup-shaped construction, (in which the cup is a segment of a sphere) but thisA cup-shaped anvil cannot predetermine or control the direction of the cleiich with any degree of accuracy, but the point of the nail is liable to turn sideWise and over the anvil sov as to come out on the side of the shoe, thus ruining the shoe. However, by forming a turned point on t-he end of the fastener` this turned point Will cause and insure that the nail be clenched inthe direction given it by this preliminary turn. The turn given the point of the nail must be slight,

and short and comparatively abrupt, other-1 Wise the nail willfcurl in the leather. Curling of the nail, even in hard leather is further prevented by irnily supporting the nail againsttransverse or tipping movement while it is being driven,- andby forming an aWl hole to receive and guide the nail.

' Referring now to `Figs. 22 and 23, which show a trans-verse section of a McKay shoe andra sectionialong the seaml as formed with this machine, l140 designates the upper, 141 the insole, 142 lthe outsole, and 143 the tapsole. These parts of the shoe are shown as secured together by means of the metallic nails of fasteners 134. The fasteners are so inserted that theheads 144 thereof Will be located in the outsole. and the clenched points 145 turned backin to the insole. The fasteners can of course be driven in a channel cut in the' outsole and the'heads thereofcovered by the channel lip. 'The-seam as madewith this machine will have the fasteners thereof extending through the outsole, tapsole, upper-and insole, with the heads vlocated inthe outsole and the clenched points turned back into the insole. These clenched points will extend in a direction along the seam, and it is possible to accurately clench the points in such a direction in view of the fact that the machine pr'edetermines the direction of -the clench. The heads of the fasteners ddnot restrict free expansion .or contraction of the fibers of the outsole when the sole is ii'exed'. The clenched points of the fasteners extend in the same direction and along the seam, -this will further enhance the flexibility l-of thesole and cause the flexureto be uniform along the sole. The sole made in accord-ancelvvith thisl invention is therefore flexible inview of the fact -that free expansion and contraction of the fibers is permitted when the sole is fiexed. Further* more the inside surface of the inside is leftl `perfectly smooth so that no socksole is retherefore to be understood thatvthis inven tionis not to be limited. to .the speciic construction shown and described.
